Hints and Tips: 

Q. What size cork do I need?

To decide which size cork you require, first, measure the inside diameter of where the cork needs to fit. As the corks are tapered you need to select a cork that has a smaller bottom diameter and a larger top diameter. (See size chart in downloads)

Q. There seems to be more than one cork that will fit which do I chose?

In this case, it will depend on how far you wish the cork to fit in. The nearer the size to the bottom diameter, more of the cork will stick out of the top. The nearer the size of the top diameter, more will fit in - less will stick out.

Q. My opening is 75mm. Which do I chose, 75mm top or 75mm bottom?

This is the awkward one, as we do not stock every variation. Although there is a tolerance of +/-mm if you purchased the 75mm top diameter it would likely fall in. The 75mm bottom diameter may not fit in at all. Our suggestion here is to take the bottom diameter option and either trim with a knife or use sanding paper to reduce the bottom area until it fits.
